    Screenshot Utility

    The screenshot utility enables developers to capture images of sideloaded channels. These images can be uploaded with a channel submission to showcase in the Channel Store after publication.

    To take a screenshot:

    • sideload a channel
    • Navigate to the screen that needs to be captured
    • Click on the screenshot button

    Screenshots will only work for sideloaded channels and static content, so screenshots of video will not work. FHD (1920x1080) screenshots also require a 4K-capable Roku set to 1080p or 4K UHD display type.

I've also noticed that on my Sharp 4K, channels running FHD, screenshots says ok but is empty like you but on my TCL which is 720p (HD) screenshot works and displays in the browser but video stream frame is not captured, so I'm guessing anything higher than HD resolution will be empty.
